ABSTRACT:
A color negative photographic element is disclosed that is constructed with the following layer unit coating sequence, starting with the support: slower red, slower green, slower blue, faster red, faster green and faster blue. A surprising enhancement in speed is realized when color development is undertaken in a time (S) ranging from 15 to 110 seconds and a development temperature (T) ranging from 40 to 65.degree. C., development time and temperature being chosen to satisfy the relationship:
